{"apiVersion":"1.0","identifier":"CVE-2026-62674","description":"Omnigent is an open-source AI agent framework and meta-harness for orchestrating coding agents. Prior to 0.3.0, PUT /sessions/{session_id}/agent checks LEVEL_EDIT permission for a session but does not reject a bound shared or template agent whose agent.session_id is None. An authenticated user with edit access to a session can replace that shared agent bundle through omnigent/server/routes/sessions.py, add a stdio MCP server, and cause later sessions that use the shared agent to launch an attacker-controlled command through omnigent/tools/mcp.py. The command executes with the Omnigent runner process permissions and can expose files, credentials, workspace data, internal services, and runner availability. This issue is fixed in version 0.3.0.","publishedAt":"2026-08-21T18:16:49","lastModifiedAt":"2026-08-25T18:17:58","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-62674","cvssScore":9,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","epssProbability":0.00343,"riskScore":0.93,"affectedProduct":"Omnigent","affectedVersions":"<0.3.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-62674","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-62674","en":"https://www.redsauce.net/en/cves/CVE-2026-62674","fr":"https://www.redsauce.net/fr/cves/CVE-2026-62674","pt":"https://www.redsauce.net/pt/cves/CVE-2026-62674","de":"https://www.redsauce.net/de/cves/CVE-2026-62674","sk":"https://www.redsauce.net/sk/cves/CVE-2026-62674","el":"https://www.redsauce.net/el/cves/CVE-2026-62674"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-62674"}}
